摘要

以10 000 TEU集装箱船为例,分别采用DNV规范中的节点力法及《油船散货船共同结构规范》(CSR)中的节点力法对其总强度进行计算。对比二者的计算结果,分析CSR节点力施加方法对集装箱船总强度评估的适用性及其优缺点。结果显示,CSR节点力施加方法适用于集装箱船总强度评估,且可有效避免局部应力集中现象。
        Taking the 10 000 TEU container carrier as an example, the nodal force method(NFM) in the DNV rules and that in the CSR are adopted respectively to calculate the global strength. By comparing the results of the two methods, the applicability and merits/faults of NFM proposed by CSR in the global strength evaluation of the container carrier are analyzed. The results show that the NFM of CSR is applicable to the global strength evaluation of container carriers and the phenomenon of stress concentration is avoided effectively.
